chore: address XGAS-01 signature validation semantics - #13
Merged
Conversation
Add SignatureValidationSemantics tests and architecture notes for encoded-signature validation behavior. - add EOA and ERC-1271 encoded-path success tests - add EIP-7702-style code-presence regression showing encoded-path rejection while classic (v,r,s) still succeeds - document SignatureChecker routing, implications, and integration guidance

Summary
Addresses XGAS-01 (#10)
Documents and tests the EIP-7702-related validation semantics of xGAS bytes-signature entrypoints that use
SignatureChecker.isValidSignatureNow.The update clarifies that bytes-signature paths intentionally follow the signer account’s current validation mode, including ERC-1271 validation when the signer has code. It also adds tests proving the distinction between encoded-signature paths and classic EIP-3009
(v, r, s)paths.Changes
(v, r, s)paths continue to use direct ECDSA validation.Notes
No production validation logic was changed. The PR documents and tests the intended design behavior.
